Convince Mojang to Improve Minecraft Character Animations

Everyone who plays the originally indie sandbox game Minecraft knows how... off the player movement animations appear at times, and some actions like swimming don't have animations at all. Now, there are many modifications devoted fans have made to the game creating fluid animations for almost every in-game action. However, what if these modifications became standard to Vanilla Minecraft? If Mojang and some talented animators added this style of animations to the game, even if the changes to some animations are slight elbow or knee movement and no more, It'd improve the aesthetic and even some of the gameplay of the game drastically, like seeing another player draw back their bow or raise their sword to swing. This is an example of what could be done if Mojang goes above and beyond with the animations.
